CD74HC132E-NG Equivalent & Substitute Parts

Part Overview

The CD74HC132E-NG is a NAND Gate IC featuring 4 channels with 2 inputs per channel and integrated Schmitt Trigger functionality, packaged in a 14-DIP through-hole configuration. Manufactured by Texas Instruments as part of the 74HC logic series, this component operates across a 2V to 6V supply voltage range with low quiescent current characteristics.

The CD74HC132E-NG is classified as obsolete. Identifying equivalent and substitute parts is necessary to support legacy system maintenance, design updates, and procurement continuity when original stock becomes unavailable.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the CD74HC132E-NG is determined by strict equivalence across the following electrical and mechanical parameters:

Electrical Equivalence Criteria:

• Logic Type: NAND Gate (4 channels, 2 inputs per channel)
• Schmitt Trigger functionality
• Supply Voltage Range: 2V ~ 6V
• Quiescent Current: 2 µA maximum
• Output Current: 5.2mA (high and low)
• Propagation Delay: 21ns @ 6V, 50pF
• Series: 74HC

Mechanical Equivalence Criteria:

• Package type compatibility (through-hole or surface-mount variants of the same base product)
• Pin count: 14 pins
• Base Product Number: 74HC132

The SN74HC132PWR qualifies as a manufacturer-recommended substitute because it maintains identical electrical specifications while offering an alternative surface-mount package (14-TSSOP) and active product status. Both parts share the same base product number (74HC132) and core functional characteristics.

Parameter Comparison

Engineering Selection Recommendations

For Direct Functional Replacement:

The SN74HC132PWR is the manufacturer-recommended substitute for the CD74HC132E-NG. Both components deliver identical electrical performance across all specified parameters: logic function, circuit count, input configuration, supply voltage range, quiescent current, output current, and propagation delay.

Package Consideration:

The primary difference is packaging: CD74HC132E-NG uses through-hole 14-DIP mounting, while SN74HC132PWR uses surface-mount 14-TSSOP. Selection between these variants depends on board design and assembly capability. Through-hole designs require the DIP package; surface-mount designs require the TSSOP package.

Product Status Impact:

The CD74HC132E-NG is obsolete, while SN74HC132PWR maintains active product status with significantly higher inventory availability (87,830 units versus 838 units). For new designs or long-term procurement, SN74HC132PWR is the preferred choice.

Operating Temperature Range:

The CD74HC132E-NG supports -55°C to 125°C operation, while SN74HC132PWR supports -40°C to 85°C. Applications requiring operation below -40°C or above 85°C must retain the original CD74HC132E-NG or identify alternative solutions outside the 74HC132 family.

Compliance:

Both parts are ROHS3 compliant, supporting environmental and regulatory requirements for modern electronics manufacturing.

Frequently Asked Questions (FAQ)

Q: Can SN74HC132PWR replace CD74HC132E-NG in an existing through-hole PCB design?

A: No. SN74HC132PWR is a surface-mount component (14-TSSOP package), while CD74HC132E-NG is through-hole (14-DIP package). Direct PCB substitution is not possible without board redesign or the use of adapter modules. For through-hole designs, identify alternative 14-DIP packaged variants of the 74HC132 logic family.

Q: Are the electrical specifications identical between these parts?

A: Yes. Both components share identical electrical specifications: 4-channel NAND gates with Schmitt Trigger, 2V to 6V supply voltage, 2 µA quiescent current, 5.2mA output current, and 21ns propagation delay at 6V with 50pF load.

Q: What is the significance of the obsolete status of CD74HC132E-NG?

A: Obsolete status indicates that Texas Instruments has discontinued manufacturing. Existing inventory may be limited and subject to availability constraints. SN74HC132PWR, with active status and 87,830 units in stock, provides procurement continuity and long-term supply assurance.

Q: Does the operating temperature range difference affect substitution?

A: Only for applications requiring operation outside the -40°C to 85°C range supported by SN74HC132PWR. If your application requires -55°C to -40°C or 85°C to 125°C operation, SN74HC132PWR is not suitable. Retain CD74HC132E-NG or identify alternative components rated for the required temperature range.

Q: Are both parts RoHS compliant?

A: Yes. Both CD74HC132E-NG and SN74HC132PWR are ROHS3 compliant, meeting environmental and regulatory standards for lead-free electronics manufacturing.

Q: What does the base product number 74HC132 indicate?

A: The 74HC132 is the base product designation for a 4-channel NAND gate with Schmitt Trigger in the 74HC logic family. Variants of this base product exist in different packages (DIP, TSSOP, SOIC, etc.) and from different manufacturers, all sharing the same core electrical function and specifications.
